First of all, remember that SPOOLED devices are not supported on diskless
workstations.  There are workarounds.

Select code 9.

Don't know about that, it should be in the plotter manual.

The serial driver, one (1).  It's automatically included in your kernel, so 
you shouldn't need to rebuild.  Use the following mknod:

# mknod /dev/plotter c 1 0x090004

This says the plotter is at select code 9 with "direct connect".

The driver defaults to 300 baud (among other things).  Your interface
script might need to change this.  (You might need to create a custom model).
Have a look at the "stty" command in one of the printer models in 
/usr/spool/lp/model (such as "laserjet"); you should find something like

# Set up RS-232 interface if this is a tty port
stty raw 9600 -parenb cs8 ixon -istrip clocal <&1 2>/dev/null

Good luck!
